The present application is a 35 U.S.C §§371 national phase conversion of PCT/US2012/043161, filed Jun. 19, 2012, claims the benefit of U.S. Provisional Patent Application No. 61/499,027, filed Jun. 20, 2011; the entire contents of which are hereby incorporated by reference herein.
The present invention relates to mycotoxins and their role in disease etiology. The present invention is directed towards reducing human diseases, conditions, and states of morbidity and mortality by detecting and inhibiting production of harmful microbes and their toxins, and in particular pathogenic fungi and yeasts, in their human or other mammalian hosts. Mammalian species are prone to contamination by pathogenic fungi that produce toxic metabolites known as mycotoxins, and create other metabolic perturbations causing disease.
The syndrome known as regressive autism is a multifaceted disease entity that can present with a multitude of protean manifestations that has defied an accepted definitive etiology to date. Common to many or most of these associated disease states is a generalized decrement in behavior and communication skills. Previously this deficiency has been attributed to heavy metal intoxication, among other suspected pathobiologies. The current invention describes actual pathogenic compounds known as mycotoxins, formed by yeasts, fungi and molds that infect and cause disease in mammals and eukaryotes. For instance, the mycotoxin gliotoxin, produced by Candida, Aspergillus and Penicillium species, among others, has been shown to rapidly bind to sulfur containing molecules and render many molecules and proteins and enzymes nonfunctional. Gliotoxin has also been shown to bind to, deplete, and oxidize glutathione, a crucial antioxidant, causing oxidative stress. Glutathione is also responsible for the effective function of the crucial enzyme systems known as metallothioneins, which are needed for metabolism and maintenance of crucial metals in the brain and other bodily sites. Aflatoxin is similarly produced by mycotoxigenic fungal species and is immunosuppressive, inhibits protein synthesis and is carcinogenic, and may be a co-factor in many of the same disease states.
The current invention is directed towards a rapid, reproducible test(s) for fungal virulence factors and associated affected compounds so that patients at risk for autism, cerebral palsy and other human diseases can be quickly identified and treated, and disease progression possibly prevented. This includes a multitude of test protocols for both the mycotoxin gliotoxin, and its relationship with glutathione, and relates the two molecules by a novel paradigm known as the Glutathione-Gliotoxin Index—(GGI) or the Disease/Disorder Susceptibility Index—(D/DSI). This relates the two molecules, with the ratio of glutathione in the preferred redox state divided by the concentration of gliotoxin present in the sample tested concurrently. Alternatively, the inverse ratio could be used, the Gliotoxin-Glutathione Index. These numerical relationships can be whole numbers, fractions, integers, decimals, and even negative numbers. The utility of said numerical ratios will be apparent when the full spectrums of aberrant toxicological and biochemical perturbations are apparent across the numerous disease states caused by this pathobiology. One testing protocol includes mass spectroscopy, including tandem mass spectroscopy, among many others. For instance, all bodily fluids and tissues are in the realm of a test paradigm for the toxigenic factor(s) and biochemical perturbations which cause neurobehavioral changes seen in autism and other disease states.
Of particular relevance for autism is the role of glutathione depletion by gliotoxin, then by the anti-pyretic acetaminophen in the peri-vaccination period, which each result in oxidative stress and metal intoxication, by disrupting the metallothionein system, amongst other biochemical pathways and enzyme systems. A numerical relationship between concentrations of glutathione and gliotoxin shall be known as the Autism Susceptibility Index—ASI.
The invention is also directed to prevention of said disease states by a multitude of methods such as competitive exclusion of gliotoxin producers by a non-toxigenic species, such as a beneficent pro-biotic. It is also directed towards treatment of said disease states by a fungistatic compound, a fungicidal compound, an ETP toxin antibody, a competitive inhibitor of said re-dox virulence factor by an anti-oxidant compound, a compound or element that neutralizes gliotoxin, such as selenium, zinc, manganese, taurine, and other minerals, enhancement of glutathione production by its precursor N-acetyl-cysteine, and addition of a toxin adsorbent to foodstuffs, among others.
It is therefore a general object of the invention to provide a novel testing paradigm, which will identify a potent fungal toxin, gliotoxin, or any epipolythiodioxopiperazine (ETP) toxin or mycotoxin, with negative public-health consequences in human disease.
It is another general object of the invention to provide novel paradigm relating the ratio of glutathione—reduced, oxidized or total—to the amount of gliotoxin present in a patient's samples. A related object of the invention is to provide a novel paradigm relating the presence and/or ratio of hydrogen sulfide present in a patient's sample. Such presence or ratio having implications with negative public-health consequences in human disease (and thus relevant for treatment, diagnosis or prevention of disease).
It is another general object of the invention to identify and quantify the Glutathione-Gliotoxin adducts and create a Glutathione-Gliotoxin Index—(GGI)—or the Disease/Disorder Susceptibility Index—(D/DSI), which also indicates the Autism Susceptibility Index—(ASI).
It is another general object of the invention to apply the GGI or D/DSI to a multitude of human diseases and conditions of current unknown etiology implicated by these indices so that said diseases can be prevented, treated and ameliorated.
It is a specific object of the invention to identify patients with a critical Autism Susceptibility Index—ASI—and to withhold acetaminophen from said patients to prevent onset of regressive autism.
It is a specific object of the invention to utilize a portable hand held electronic device, such as a cell phone, I-Pod, I-Pad, Android phone, or the like, with an attached or integrated module to test for said toxins, and a computer algorithm which computes levels of compounds tested for.
It will become apparent to one skilled in the art that said methods and processes will have inherent utility when a significant virulence factor in autism and other human diseases is tested for, treated, and the syndrome prevented, and said invention will have obvious value over the scant prior art.

Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.
Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.
Injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.
In order to prolong the effect of a provided compound, it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered compound form is accomplished by dissolving or suspending the compound in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the compound in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of compound to polymer and the nature of the particular polymer employed, the rate of compound release can be controlled.

A clinician skilled in the art can readily identify such candidate patients, by the use of, for example, clinical tests, physical examination and medical/family history.
A method of assessing the efficacy of a treatment in a subject includes determining the pre-treatment extent of a disorder by methods well known in the art (e.g., determining tumor size or screening for tumor markers where the cell proliferative disorder is cancer) and then administering a therapeutically effective amount of a compound of the invention, to the subject. After an appropriate period of time after the administration of the compound (e.g., 1 day, 1 week, 2 weeks, one month, six months), the extent of the disorder is determined again. The modulation (e.g., decrease) of the extent or invasiveness of the disorder indicates efficacy of the treatment. The extent or invasiveness of the disorder may be determined periodically throughout treatment. For example, the extent or invasiveness of the disorder may be checked every few hours, days or weeks to assess the further efficacy of the treatment. A decrease in extent or invasiveness of the disorder indicates that the treatment is efficacious.

Provided compounds can besides or in addition be administered especially for tumor therapy in combination with chemotherapy, radiotherapy, immunotherapy, phototherapy, surgical intervention, or a combination of these. Long-term therapy is equally possible as is adjuvant therapy in the context of other treatment strategies, as described above. Other possible treatments are therapy to maintain the patient's status after tumor regression, or even chemopreventive therapy, for example in patients at risk.
Such additional agents may be administered separately from a composition containing a provided compound, as part of a multiple dosage regimen. Alternatively, those agents may be part of a single dosage form, mixed together with a provided compound in a single composition. If administered as part of a multiple dosage regimen, the two active agents may be submitted simultaneously, sequentially or within a period of time from one another normally within five hours from one another.
Upon improvement of a subject's condition, a maintenance dose of a compound, composition or combination of this invention may be administered, if necessary. Subsequently, the dosage or frequency of administration, or both, may be reduced, as a function of the symptoms, to a level at which the improved condition is retained when the symptoms have been alleviated to the desired level, treatment should cease. The subject may, however, require intermittent treatment on a long-term basis upon any recurrence of disease symptoms.
It will be understood, however, that the total daily usage of the compounds and compositions of the present invention will be decided by the attending physician within the scope of sound medical judgment.

Pathobiology of Disease Implicated by the (GGI) or (D/DSI)
Glutathione loss by the fungal toxin Gliotoxin, then Acetaminophen in the peri-vaccination period, results in Metal Intoxication and Oxidative Stress-causing Regressive Autism.
Toxicity of Acetaminophen (APAP): is the most widely used analgesic worldwide. It is the most common cause of accidental poisoning and liver failure and became commonly used in early 1980s due to concern aspirin was causing Reye's syndrome. Coincident with the new use of APAP was the rapid rise of Autism cases. Acetaminophen overdose occurs when conjugative pathways become saturated. APAP is then oxidatively metabolized by liver p450 to NAPQI which normally is conjugated with glutathione and renally excreted.
Acetaminophen Pathophysiology: when glutathione levels are reduced, NAPQI binds to lipid hepatocytes and vital proteins, causing Oxidative Stress, inflammation and hepatocellular Zone III necrosis. The treatment for APAP overdose is N-Acetylcysteine—NAC, a glutathione precursor, and may enhance sulfate conjugation of free APAP. N-AC is also anti-inflammatory, an antioxidant, and increases Nitric Oxide levels and local tissue oxygen tensions—pO2. N-AC is best given within 8 hours, decreasing mortality. A new IV version called Acetadote is now currently available with expected improved outcomes.
Oxidant Stress, Reactive Nitrogen Species and APAP Toxicity: APAP depletes Glutathione (GSH) and binds to cellular and mitochondrial proteins. This inhibits and stresses mitochondrial respiration, causing ATP depletion. When Vitamin E is present, ROS do not induce lipid peroxidation, but superoxide anion reacts with Nitric Oxide—NO—to form peroxynitrite, thus modifying cell molecules and worsening mitochondrial dysfunction and ATP depletion. This known liver model is likely worse in the brain due to the dependence of the brain on blood borne glutathione. Neuronal Cells in the brain are wholly dependent on circulating blood borne Glutathione. Hence if circulating blood glutathione levels drop to below a critical level the brain is “starved” of glutathione, ATP, Oxygen use and localized cellular death is seen, as in Cerebral Palsy, which is characterized by Periventricular Leukomalacia—PVL. CP-PVL may represent the early extreme of a continuum of neurological syndromes of which Regressive Autism occurs at 24 months in the peri-vaccination period for MMR—mumps-measles-rubella vaccine.
Glutathione and Analgesics: GSH is a vital antioxidant, as it detoxifies drugs and reactive Oxygen species—ROS, regulates gene expression and effects membrane transport and apoptosis. Homeostasis is critical as turnover of GSH is dynamic; the precursors are the amino acids cysteine, glutamic acid and glycine. Toxic APAP levels deplete GSH, where depleted Glutathione is seen in AIDS, alcoholics, atherosclerosis, dyslipidemia, renal disease, malnutrition, cirrhosis, hepatitis, Pregnancy Induced hypertension—PIH, Eclampsia, Pre-eclampsia, and Toxemia of pregnancy, HELLP Syndrome, Gestational Diabetes, Diabetes, Cerebral Palsy, Peri-Ventricular Leukomlacia, Neonatal Jaundice, Bronchopulmonary Dysplasia, Multiple Sclerosis—MS, Macular Degeneration, Alzheimers, Parkinsonism, Amyotrophic Lateral Sclerosis, Schizophrenia, Ionizing Radiation poisoning, and other diseases of humans.
APAP, Measles, Mumps, Rubella (MMR) Vaccine & Autism: Schultz (UCSD) et al. (Autism—May 2008) using an on-line case control study surveyed 83 Autism families and 80 controls. APAP after MMR was significantly associated with Autism at O.R=6.1 (less than 5 y.o.). With Autism Regression only the O.R. was 3.97 and with post-vaccination sequelae only the O.R. was 8.23. Ibuprofen showed no association. Therefore, APAP after MMR is associated with Autism.
APAP Induced Oxidative Stress: Protection is afforded by N-Acetylcysteine: APAP increased cell and mitochondrial glutathione disulfide (GSSG) and altered GSSG: GSH ratio suggesting an oxidative stress role. Autistic children have elevated oxidized/reduced GSH ratio where normal children have 100 to 1 ratio of Reduced GSH to Oxidized GSH, this ratio is reversed in Regressive Autism children. Treatment with N-Acetyl Cysteine—a glutathione precursor—enhanced cell glutathione and reduced cellular loss. APAP-Oxidative Stress precedes cellular injury and is involved in spread of cell injury.
Oxidative Stress, Mitochondria and Glutathione Protection: Mitochondria provide energy and are involved in cell death by apoptosis. Oxidative phosphorylation generates Reactive Oxygen Species—ROS—from the electron transport chain. Superoxide anion and hydrogen peroxide—H2O2—are produced by transition metals in aerobic respiration. GSH in mitochondria is the only defense to H2O2. Glutathione is required to move GSH from the cytosol to the mitochondria. Glutathione transport is stabilized by Selenium-Adenosyl Methionine (SAM). Hence treatment for Autism should involve administration of Selenium and Methionine.
SAM and NAC are Protective against APAP Hepatotoxicity: SAM and NAC were compared in the treatment of APAP toxicity. In one study SAM was more protective than NAC. The Cysteine/Glutamate exchange modulates Glutathione supply for neuroprotection against Oxidative Stress. Glutathione synthesis is limited by Cysteine. NAC, SAM and GSH treatment raise Erythrocyte GSH. E-GSH may be cheapest—quick screening test for Autism susceptibility as most Glutathione is located in RBCs. Testing for GSH in RBCs could involve special preparation, such as freeze-drying and fracturing to release the intracellular contents. Anemia of pregnancy may be due to lysis of erythrocytes-RBCs by gliotoxin from Candida and other species.
Sulfate Metabolism is Abnormal in Autistic Children: Sulfation is important in metabolism of neurotransmitters and digestive hormones. Children with Autism had low APAP/sulfate glucuronide level—suggesting decreased sulfation capacity in the liver. This is associated with increased urinary sulfite and sulfate excretion. Sulfate metabolism defects in Autistic children are likely acquired due to fungal infestation and resultant mycotoxin production.
Glutathione Metabolism in CSF and the Blood Brain Barrier: Glutathione in the Choroid Plexus is metabolized like urine in the tubule in kidneys. CSF GSH can be modified by drugs that do not affect brain GSH. GSH mono-ethyl ester can be transported into CSF posing a possible potential treatment. Gamma-Glutamyl transpeptidase, which is high in the choroid plexus, is the only enzyme able to cleave the gamma-glutamyl bond of glutathione. Brain mitochondrion is more susceptible to GSH loss and Oxidative Stress than liver. H2O2, if not reduced, can lead to lipid hydroperoxides, damaging the mitochondrial membranes and their function. Autistic children show loss of Purkinje Cells and Increased Brain Volume.
Glutathione Redox State Regulates Mitochondrial Reactive Oxygen: Impaired Glutathione stores in Brain further increase mitochondrial ROS causing a cascade of further damage. To function as an antioxidant, Glutathione must be in the reduced form—to act as an electron donor. Normally there are 100 reduced GSH molecules vs. oxidized. Autistic patients have mostly oxidized GSH.
Glutathione Loss, Oxidative Stress and Metabolic Errors in Autism: Autistic children have Immune, Digestive, and Metabolic Abnormalities, i.e. low plasma inorganic sulfate and sulfur oxidation deficiencies. Irritable Bowel Disease (IBD) patients have low GSH—this deficiency may be a target for intervention. Many Autistic children have GI abnormalities and have bowel yeast/fungal issues such as GI Candidiasis producing ETP like toxins, such as Gliotoxin. Intrinsic defects in Immunity are seen in GI positive Autistic Syndrome Disorder (ASD) Children. Gliotoxin has been shown to kill CD4 cells, and in fact Autistic children have decreased CD4 cell counts and generalized immune suppression as seen in AIDS.
Oxidative Stress in Autism: This work has been done by A. & V. Chauhan who found Lipid Peroxidation markers are elevated in Autism. Transferrin (Iron binding) and Ceruloplasmin (Copper binding) levels are decreased, leading to altered Fe and Cu metabolism with sequelae. Antioxidant-Serum proteins are decreased, i.e. albumin, total protein which is seen also in Eclampsia, HELP Syndrome, Cancers, AIDS and others. Other enzymes altered include superoxide dismutase (SOD), glutathione peroxidase, catalase, homocysteine, methionine, farnesytransferase, causing inflammation, excitotoxicity, mitochondrial and generalized immune dysfunction. Alkaline phosphatase is elevated in many of these syndromes including Cerebral Palsy—CP, and alkaline phosphatase has been shown to be elevated after administration of Gliotoxin to camels.
GSH Determines Sensitivity toward Mercury-Hg-Induced Oxidative Stress: Cortical and Cerebellar Areas exhibit differential sensitivity to Mercury-induced ROS. Methylmercury (MeHg) is highly neurotoxic. GSH protects against MeHg neurotoxicity in neurons and astrocytes. Depletion of GSH increases MeHg toxicity and stress. GSH precursors—NAC & SAM—are neuroprotective. Acetaminophen—APAP, Gliotoxin and Mercury-Hg—are synergistic in Autism.
Thimerosol & Impaired Mitochondrial Oxidation/Reduction Activity: Ethyl-mercurithiosalicylic acid is an Ethyl-Hg releasing compound and has been in use 70 plus years. Thimerosol is 50% Mercury and thimerosol neurological damage is similar to that seen in Autism. TM is a preservative used in multi-dose vaccines. TM was removed from most vaccines in 2002 but the Autism epidemic continues unabated. Many vaccines still contain metals, such as vaccines given to newborns and many contain Aluminum as an adjuvant. Salicylates were linked to Mitochondrial Re-Dox impairment in Reye's syndrome as salicylates uncouple mitochondrial oxidative phosphorylation, as does Gliotoxin. Aspirin and Gliotoxin may act synergistically to cause Reye's syndrome. The role of aspirin in Reye's syndrome has been largely discredited. Once aspirin use was discouraged, the use of Acetaminophen soared and the Autism Epidemic began.
Candida and Aspergillus species yeasts produce Gliotoxin. Gliotoxin is immunosuppressive by killing CD4 cells, possibly causing AIDS and disrupts many enzyme systems. 32 of 50 of Candida tested produced an ETP-epipolythiodioxopioperazine-like compound. Gliotoxin, a hydrophobic molecule, was found in many cancer patients at MD Anderson in amounts far in excess of that required to cause pathology. 93% of Aspergillus fumigatus, 75% of A. niger and 25% A. terreus produced Gliotoxin. A. fumigatus had the highest concentrations of GT. Penicillium and Trichoderma can also make Gliotoxin. Other ETP toxins produced by fungi include Sirodesmin, Hyalodendrin, Spoidesmin A, Chaetomin, Chaetocin, Verticillins, Leptosin, Emestrin, Scabrosin, Dithiosilvatin, Epicorazine, Aranotin, Emethallicin. The methods herein can utilize any ETP toxin or other toxigenic mycotoxin, including those specifically delineated herein.
Gliotoxin Toxicity and Mode of Action: The toxicity of ETPs is due to the presence of the disulphide bridge, which inactivates proteins via reaction with thiol groups, and generation of ROS by Redox cycling. Gliotoxin possibly reacts with disulphide cysteine bonds in insulin causing loss of function and diabetes. Gliotoxin suppresses T-Cell response, inhibits the antigen presenting response and led to a preferential death of monocytes and derived dendritic cells as seen in AIDS. Physiological effects of GT are way below levels of GT found in cancer patients. Gliotoxin is a dangerous molecule. Gliotoxin production by A. Fumigatus may be an immunoevasive mechanism, acting on T cells.
Gliotoxin Pathobiology: Gliotoxin inactivates muscle Creatine Kinase—CK—by a reversible formation of a Disulfide Bond. CK is coupled to the regeneration of ATP to ADP and the Mitochondrial Permeability Pore (MPP). The Gliotoxin disulphide bond reacts with accessible cysteine residues on proteins, enzymes, hormones and synaptic receptors. Thus, there is a synaptic role in Autism also. GT inhibits alcohol dehydrogenase, reverse transcriptase, farnesyltransferase, and alters transcription factor NF kappa B. GT may similarly inactivate insulin in Gestational Diabetes and alter Nitric Oxide signaling, causing pregnancy induced hypertension—PIH. Bioactivity may be restored when treated with reducing agents as the oxidized forms showed loss of function. GT production and growth of human pathogenic yeasts in general, is favored by sex-steroid metabolism, such as progesterone, as seen in pregnancy, and by estrogen and testosterone.
Gliotoxin-Glutathione Adducts Deplete Physiological GSH Stores: Mechanism of Action of GT is disulfide linkage with sulfur nucleophiles in a thiol-disulfide exchange mechanism. GT/GSH equilibrium depends on pH and GSH level. Depletion of GSH by GT has numerous pathophysiological consequences. There is a ReDox dependent mechanism for GSH dependent reversible uptake of GT in cells. GT uptake to cells is dependent on GSH, and a 1500 fold increase of reduced GT is found intracellularly, as opposed to outside the cell. Oxidation of intracellular GT effluxes GT, and the efflux of GT is also caused by low GSH from cellular apoptosis. The above allows for a minor Gliotoxin production, while causing a maximum intracellular concentration, yielding maximum killer efficacy against a competitive organism. Decreased intracellular Glutathione after apoptosis by GT releases more GT for further cell killing like a “PacMan”, devouring cells and then moving on to the next cell.
Metallothionein—MT—is regulated by Oxidative Stress and Metal Ions: MTs are small cysteine-rich (30%) heavy metal binding proteins which protect against stress and regulate Zinc and metal levels. Cysteine residues bind and store metal ions, such as Zn, Cu, Cd and others, such as mercury. MT has antioxidant capabilities and MT deficient knockout mice are sensitive to APAP hepatotoxicity. APAP and Gliotoxin deplete Glutathione, essentially creating Metallothionein deficient Autistic children.
Metallothionein and Zinc: MTs are involved in zinc metabolism: This control is linked to cellular Glutathione Status. Glutathione disulfide S-thiolation causes MT clusters to collapse and release Zinc. Zinc is released by oxidants, and antioxidants preserve this binding. A GSH/GSH disulfide redox coupling mechanism and selenium effect zinc delivery. Oxidation-Reduction state is critical to the direction of zinc transfer and distribution. MTs regulate mercury neurotoxicity, esp. MT III. MT perturbations are seen in Periventricular Leukomalacia—PVL, the hallmark of Cerebral Palsy—CP. This is associated with Premature Rupture of the Membranes—PROM—which is often treated with antibiotics, resulting in fungal overgrowth and production of mycotoxins, such as Gliotoxin. Treatment of patients with Cerebral Aspergillosis producing Gliotoxin have shown improvement in their condition by administration of intrathecal Glutathione via the cerebrospinal fluid—CSF.
Zinc Induced Neuronal Death is a possible pathology in Autism: Intracellular free zinc contributes to energy failure by loss of NAD+ and inhibition of glycolysis, prior to Mitochondrial Permeability Transition (MPT), inducing neuronal cell death. Zinc neuronal death is attenuated by oxaloacetate, dichloroacetate and niacinamide, which are possible treatments for Autism and CP. Zinc inhibits mitochondrial respiration at bc1 and alpha-ketoglutarate-dehydrogenase. Zinc is a novel intracellular second messenger with likely implications when disrupted.
Synaptic Cysteine Sulfhydryls are targets of Neurotoxicants: Sulfhydryl reactive metals (Hg, Cd, As, Pb) in the hair of Autistic children has been found lower than controls, leading to the conclusion these children had trouble excreting these metals. Impaired MT processing may be the etiology. These metals are likely bound to neurotransmission sites or other critical areas in Autistic children—causing the pathobiology.
Brain Neurotoxicity: Astrocytes are essential to provide GSH precursors to neurons. Thimerosol neurotoxicity is associated with GSH depletion. GSH provides defense against mercury toxicity. NAC & glutathione ethyl ester prevented cytotoxicity. GSH is poorly absorbed via GI tract so other routes must be chosen. These include transdermal, transnasal, IV, IM, oral based lipoceutical formulations, and others. There is a role for other neuroprotectants (SAM, B6, B12, thiamine, methionine etc.) Deficiency of thiamine can cause Werneke-Korsakoff Syndrome which leads to apoptosis—cell death—of neurons. Autism children have been shown to benefit from thiamine formulations.
The Etiology of Autism—Summary and Conclusions: Antibiotic Therapy changes GI flora favoring toxic yeasts. Antibiotics can also decrease the ability to detoxify metals by 90%, especially mercury. Gliotoxin is produced by the new GI flora by Aspergillus and Candida. Medicinal production in manufacturing of acetaminophen in facilities introduced Aspergillus spores into the end products as evidenced by formation of 2,4,6-tribromoanisole, which is formed by Aspergillus, most likely capable of Gliotoxin production. This resulted in a musty-moldy odor, which led to a massive product recall. Gliotoxin then adducts and depletes Glutathione to marginal levels. When GSH is less than 30% of normal or oxidized, APAP becomes toxic. Acetaminophen—at perivaccination period—is then associated with Critical Glutathione loss, especially in the brain by crossing the blood brain barrier—BBB. Gliotoxin and APAP both cause oxidative stress. GSH is needed for metal metabolism Thus, metallothionein—MT—and most metal metabolism and multiple enzyme pathways are affected, compounding the toxicology. This causes a “Perfect Storm” of Oxidative Stress, GSH Depletion, and Zinc and metal toxicity (Hg-Thimerosol), creating a condition of mitochondrial dysfunction in the brain—leading to hypoxia and Autism—similar to carbon monoxide—CO—poisoning. This also results in neurite pruning at a period of critical neurodevelopment which has long term consequences, as evidenced by axonal neuropathy and resultant Cerebral Palsy—CP. Multiple pathways of pathobiology possibly indicate multiple therapeutic modalities and preventive approaches, e.g. precursors, vitamins, avoidance of acetaminophen, etc.
Mycotoxins in general and aflatoxins in particular, are monitored and controlled in agricultural feed and foodstuffs to minimize their impact. Current Food and Drug Administration (FDA) regulations ban use of aflatoxin-contaminated corn and grain when aflatoxin levels exceed 20 parts per billion (ppb) and 0.5 ppb for milk. Similar regulations apply for other mycotoxins. Only as of 2009 has FDA had authority to regulate tobacco and as of 2012 mandated permissible levels of these toxins on all tobacco products. Presently there is no regulatory oversight to ensure that consumer products are adequately screened and treated for mycotoxins, such as aflatoxins, and gliotoxin. Furthermore, there is no publicly available information which reveals that adequate measures are being taken by industry to monitor, treat and remove these potent toxins and prevent fungal spore forming contamination of consumer products.
Modified Risk Tobacco Products—MRTPs—will benefit tobacco consumers, secondhand smokers, and the public at large. Specifically, regulation of mycotoxins in general and aflatoxin in particular will provide substantial public health benefits. Aflatoxin is a fungal toxin produced by Aspergillus and Penicullium fungi and is a complex aromatic heterocycle decomposing at 561 degrees Fahrenheit. Aflatoxin has been shown to survive in environmental tobacco smoke. Aspergillus is found worldwide as a storage fungus and production is favored by heat and humidity. Aflatoxin has been regulated by the FDA on all agricultural commodities such as milk, corn, grain, and peanuts since 1966, but, surprisingly, not on tobacco.
Hundreds of internal documents discovered in tobacco litigation along with others give us insight into work done in this area from the 1960s through today. More recently, p53 tumor suppressor gene research is evidence of aflatoxin contamination of tobacco. P53 is the guardian of the genome which instructs genetically-damaged cells to repair or die via apoptosis. P53 is the most common mutation in all cancers, and most laboratory cancer experiments use aflatoxin to mutate p53 as a positive control. The World Health Organization IARC (WHO-IARC) database analysis shows substantial mutations in human cancers consistent with an aflatoxin etiology. Most cancers show p53 mutations, especially lung, breast, and others. These may be due to aflatoxin, chemically known as a benzopyran, or to combustion of aflatoxin, leading to benzopyrene. Significantly, aflatoxin is 200 times more carcinogenic than benzopyrene, also a recognized tobacco carcinogen. Acting alone, aflatoxin or fungal toxigenic spores, which are semi-fire-resistant, may produce toxins in vivo, acting as infectious cancer foci. Focal Aspergillus spores, producing aflatoxin, mutate p53, while gliotoxin production would kill white blood CD4 cells, and generally be profoundly immunosuppressive, as seen in cancer. As such, aflatoxin and gliotoxin are biomarkers of toxin-producing fungal spores which may cause cancer in vivo. Additionally, they may colonize the human gastrointestinal—GI—tract where said toxins are produced and be taken up via the enterohepatic circulation, where they are ideally detoxified in the liver. However, if abnormalities in nutrients, minerals and antioxidant status are altered these toxins wreak havoc on their mammalian-human host. Aflatoxin is a carcinogen, teratogen, mutagen, inhibitor of protein synthesis, and is immunosuppressive. Aflatoxin and gliotoxin have been shown to increase HIV levels 500 percent, and both cause oxidative stress, an important emerging pathological state.
Therefore, aflatoxin and gliotoxin fungal-contaminated tobacco are likely contributing to the AIDS pandemic and numerous other human diseases by causing colonization of their host with mycotoxin producing yeasts and fungi. Other mycotoxins on tobacco are also potentially significant. In 1969, at North Carolina State, Welty performed intraperitoneal—IP—mouse injections of tobacco fungal extracts grown on baby food. A high percentage of toxic isolates causing death were found. After curing, Aspergillus was the most toxic with a lethality of 81 percent. Alternaria from brown spot disease has been shown to cause COPD in mice. Penicillic acid causes DNA breaks, possibly causing cancer. Aspergillus, Candida, and Penicillium produce gliotoxin, depleting glutathione, which is implicated in Autism, HIV/AIDS, and cancer, via disruption of the crucial enzyme glutathione-S-transferase. Undoubtedly, there are many unappreciated mycotoxins associated with tobacco use with significant repercussions for MRTPs, the FDA, and the public health. A future regulatory framework through the FDA Center for Tobacco Products—CTP—would seek to regulate toxin levels on tobacco products in a manner similar to foodstuffs.
Aflatoxin or mycotoxin contaminations of tobacco are prime candidates for harm reduction strategy in implementation of MRTPs. Multiple technology solutions are available to limit the production of toxins on tobacco and consumer products. Monitoring of aflatoxin and mycotoxin contaminations from different curing practices will provide valuable data. Prevention, remediation, and terminal testing will result in a less harmful product, improving public health. Mycotoxin bioinformatics will yield insights into cancer etiologies, new therapies, diagnostic tests, and cures for many human diseases of current unknown etiology. If MRTPs are implemented, the individual consumer, second-and third hand smokers, will benefit through a less toxic product with less cancers, and other human diseases which are caused, promoted or enhanced by these mycotoxins. These include all the above mentioned diseases which are caused by glutathione depletion by gliotoxin and citrinin.
A number of alternative assaying techniques may be used to continuously or intermittently monitor levels of toxins. These assaying techniques include, but are not limited to, high-pressure liquid chromatography (HPLC), reversed-phase liquid chromatography and HPLC, RP-HPLC/UV detection, thin-layer chromatography, radioimmunoas say (RIA), antibody-linked RIA, ELISA, spectrophotometry, mass spectroscopy—MS, tandem MS, ES-MS, infrared spectroscopy, raman spectroscopy, lyophilized ligand-receptor complexes for assays and sensors, packed-flow cell fluorescence liquid chromatography (PFCFLC), antibody-linked immunoassay, adsorption chromatography, immunoaffinity chromatography, supercritical fluid extraction, bio-luminescence, chemical luminescence, NMR isotopic S35 labeled quantification, radioactive scintillation, chiro-optical spectroscopy, polarimetry, optical rotatory dispersion, circular dichroism, and circularly polarized luminescence, use of Ellman's reagent followed by UV-vis measurement, and others. Such testing methods are found in USPTO patent assigned to Lane—U.S. Pat. No. 6,058,940, as cited above.
With particular reference to gliotoxin, desired sample materials may be freeze fractured, osmotically, or otherwise removed from erythrocytes. This then allows for pH adjustment to effect optimum extraction, prior to reversed phase HPLC analysis, where retention times for gliotoxin are 17 minutes versus reduced gliotoxin at 15.8 minutes. This is adequate enough to enable accurate integration of the areas under the curve representing the quantity present. Using HPLC analysis with a UV spectrophotometer a 260 nM wavelength is desirable. The present invention also is directed to the entire class of ETP—epidithiapiperazinediones—toxins which have in common the unique di-annular disulphide bridge which is responsible for their toxicology. There are presently seventeen such known ETP mycotoxins, and it will be obvious to one skilled in the art that it is desirable to suspect these toxins may mimic gliotoxin in terms of pathobiology, but will not be detected if one is seeking only gliotoxin through an HPLC, MS, or other testing modality that is specific for gliotoxin only. Therefore, one further testing modality includes an antibody directed towards the active disulphide moiety of the ETP toxin. Said antibody, when coupled appropriately to a ligand, reagent radio-labeled target etc, will attach to said ETP toxin and allow for identification of same. See U.S. Pat. No. 4,772,551 to Hart et al., entitled “Method and Test Kit for Detecting a Trichothecene Using Novel Monoclonal Antibodies”; and U.S. Pat. No. 4,835,100 to Dixon et al. entitled “Method and Test Kit for Detecting an Aflatoxin B1 and G1 Using Novel Monoclonal Antibodies.”
With respect to MS—mass spectroscopy—it will be apparent to one skilled in the art that Glutathione-Gliotoxin complexes with specific atomic mass units (AMUs) are within the realm of the invention, as are other Glutathione-ETP toxin mass spectroscopy atomic mass unit composites that might be found in test samples, which will vary widely as ETP toxins are of numerous AMUs.
In another embodiment of the invention, the skin or transparent fluids of the eye may be irradiated with optical radiation of a desired wavelength delivered and/or sensed, possibly through a fiber-optic device. In this, a continuous readout involves use of fiber-optic fibers or strands to carry and receive optical radiation used in the toxin identification process. The illumination apparatus may be located at a considerable distance from the point of toxin identification. Advantageously, use of fiber optics allows a plurality of wavelengths of light in close proximity to each other to be used for multiple toxin identification, and for a plurality of receiving fiber strands to be placed adjacent to each other, if necessary or desirable. The fiber optics may advantageously be mated to an electro-optical processing unit such that incident optical radiation is converted into an electrical analog or digital data stream, and the data is then transmitted electrically to a computer processing unit. In this, the test medium is illuminated at various specific frequencies and the reflected fluorescing radiation is transmitted back to a central computer. A program or algorithm designed to signal the presence of predetermined levels of toxins or other undesirable chemicals is preferably used to monitor levels of toxins in a living patient.
A further embodiment of the invention uses a cellular phone, I-phone, Android phone or other portable device to illuminate the skin, eye or other body part with a wavelength of light, and receives the reflected light signal back and sends the data via wired or wireless transmission to a computer which then interprets data and provides a readout indicative of toxin adduct status or content. Once the alert to excessive levels of toxin contamination is given, further treatment steps can be undertaken. The invention also includes administration of a chemical, compound, or pharmaceutical which will enhance identification of the desired toxin complex after a baseline level is established. See. U.S. Pat. No. 3,763,374 to Tiffany et al. entitled “Dynamic Multistation Photometer-Fluorometer.” Laser produced ultraviolet light is transmitted by fiber-optic cable (U.S. Pat. No. 3,992,631 to Harte, entitled “Fluorometric System, Method and Test Article”) to illuminate, for example, aflatoxin-specific antibody-coated beads in the cuvetettes. The toxin-specific antibody-coated beads may be coated with antibodies specific to any toxin that is to be detected. The beads are contacted with effluent solvent, which is introduced in the cuvettes via inlets. The antibody bead-cuvettes preferably use fluorescent probes, which, when combined with antibodies for specific toxins, will fluoresce even if the toxin in question does not fluoresce well or at all. An accelerator reagent may be used, if desirable or necessary, and the cuvettes may be agitated, heated or otherwise treated to enhance assay sensitivity, as with addition of a cyclodextrin. Cepeda, A., et al., “Postcolumn Excitation of Aflatoxins Using Cyclodextrins in Liquid Chromatography for Food Analysis.” Journal of Chromnatography, 1996; 721: 69-74.
Test cuvettes may be preloaded with toxin-specific antibody fluorescent probe complexes (TSAFPC) (Haugland, Richard P., Handbook of Fluorescent Probes and Research Chemicals, Sixth Ed. Molecular Probes, Inc., Eugene, Oreg., 1996) with pre-sealed needle-penetrable rubber stoppers, or test cuvettes may be loaded with toxin-specific antibody fluorescent probe complexes (TSAFPC) through inlet means just prior to testing a sample. An advantage of point of testing loading (POTL) of cuvettes is that the desired test may be chosen by a suitably programmed computer depending on the anticipated or suspected toxin and quantities present.
The toxin-specific antibody fluorescent probe complexes (TSAFPC) may be coated onto transparent microspheres of various sizes to obtain optimal fluorescence, thereby enhancing detection sensitivity. The TSAFPC-coated microspheres may be used in test cuvettes, as described above. Alternatively, the TSAFPC-coated microspheres may be affixed to a suitable substrate and used in the manner described above. Moreover, as another embodiment, the TSAFPC-coated microspheres may be introduced into a flowing solvent stream, captured by a restrictive or screen-type device, and illuminated with suitable optical radiation, and thereby, assayed. U.S. Pat. No. 4,181,853 to Abu-Shumays et al., entitled “Liquid Chromatography System with Packed Flow Cell for Improved Fluorescence Detection”; and U.S. Pat. No. 5,322,799 to Miller, Robert J. and James D. Ingle, entitled “Observation Cell and Mixing Chamber.”
In addition to Gliotoxin, many other mycotoxins such as Aflatoxin, Citrinin, Sirodesmin, Hyalodendrin, Spoidesmin A, Chaetomin, Chaetocin, Verticillins, Leptosin, Emestrin, Scabrosin, Dithiosilvatin, Epicorazine, Aranotin, Emethallicin, Penicillic Acid, each which have their own specific excitation-emission frequencies or mass spectroscopy characteristics are thus subject to detection and potential treatment. Fungi known in particular are the species Fusarium, which produce zearealone, an estrogenic carcinogen. Aspergillus ochraeus can produce a mycotoxin known as ochratoxin, which is both a nephrotoxin and promoter of lung tumors.
As depicted in the Examples below, in certain exemplary embodiments, compounds are prepared according to the following general procedures. It will be appreciated that, although the general methods depict the synthesis of certain compounds of the present invention, the following general methods, and other methods known to one of ordinary skill in the art, can be applied to all compounds and subclasses and species of each of these compounds, as described herein.
A blood sample is taken from an infant at 20 months who has had numerous bouts of otitis media with antibiotic treatment, and is at risk for GI yeast overgrowth. He may have oral thrush or Candidiasis. The sample is subjected to analysis for the qualitative and quantitative presence of glutathione (A), and the qualitative and quantitative presence of gliotoxin (B) using mass spectrometry. Upon determination of the levels of glutathione and gliotoxin, the ASI is calculated by dividing (A) by (B). An ASI of 10 or less indicates that the subject is at risk of autism and intervention is necessary. The subject is administered an agent that alters the ASI.
A blood sample is taken from a pregnant parturient at sixteen weeks into her pregnancy. The sample is subjected to analysis for the qualitative and quantitative presence of glutathione (A), and the qualitative and quantitative presence of gliotoxin (B) using mass spectrometry. Upon determination of the levels of glutathione and gliotoxin, the G/GI is calculated by dividing (A) by (B). A G/GI of 10 or less indicates that the subject is at risk for Eclampsia/Pre-eclampsia/Pregnancy Induced Hypertension and intervention is necessary. The subject is administered an agent that alters the G/GI.
A blood sample is taken from a premature neonate in the NICU, where the neonate is 26 weeks post-conception age and the mother has had PROM—Premature Rupture of Membranes—for two weeks. The neonate is at risk for Candidiasis due to administration of antibiotics to the mother for PROM. Candida producing gliotoxin depletes Glutathione and possibly subjects the neonate to PVL—peri-ventricular leukomalacia and CP—Cerebral Palsy. The sample is subjected to analysis for the qualitative and quantitative presence of glutathione (A), and the qualitative and quantitative presence of gliotoxin (B) using mass spectrometry. Upon determination of the levels of glutathione and gliotoxin, the G/GI is calculated by dividing (A) by (B). A G/GI of 10 or less indicates that the subject is at risk for PVL-CP and intervention is necessary. The subject is administered an agent that alters the G/GI.
A blood sample is taken from a patient with AIDS. Gliotoxin has been shown to kill CD4 cells and return of immunocompetence is enhanced by adequate glutathione levels. The sample is subjected to analysis for the qualitative and quantitative presence of glutathione (A), and the qualitative and quantitative presence of gliotoxin (B) using mass spectrometry. Upon determination of the levels of glutathione and gliotoxin, the G/GI is calculated by dividing (A) by (B). A G/GI of 10 or less indicates that the subject is at risk for increased morbidity and mortality and intervention is necessary. The subject is administered an agent that alters the G/GI.
